PRODUCT SUMMARY

CX20524 Mixed Signal Device for GSM and GPRS

Applications

•

GSM handsets and modules (850/900/1800/1900 MHz)

•

GPRS handsets and modules (850/900/1800/1900 MHz)

Description

The CX20524 Mixed Signal Device (MSD) is a highly integrated

device designed for use in multi-band Global System for

Mobile communications (GSM) and General Packet Radio

Service (GPRS) handsets. The MSD includes all the power

management, voice-band, mixed signal, and radio control

functions required in a GSM/GPRS handset and module.

In the receive path, the MSD digitizes the baseband In-

Phase/Quadrature (I/Q) inputs. Digital samples are then sent to

the Baseband Processor (BP) via the Rx serial interface. The

receive path features a programmable gain amplifier (PGA) for

Automatic Gain Control (AGC) of the receive signal.

In the transmit path, bursts of digital data are input to the MSD

over the control port. A Gaussian Minimum-Shift Keying

(GMSK) modulator generates modulated I and Q waveforms

from the input data. The I and Q waveforms are converted into

analog waveforms and output from the MSD.

The CX20524 generates an analog signal to control the

handset Power Amplifier (PA) output level.

The device voiceband Codec section provides an interface to a

Ω

handset speaker and microphone. Line In/Out signals are

also available to interface with audio accessories, such as a

headset or car kit.

The MSD is designed to operate directly from a single cell,

3.6 V Li Ion battery with no external regulation required. The

MSD integrates all necessary Low Drop Out (LDO) voltage

regulators that generate the required device and system power

supplies from battery input.

An integrated SIM interface circuit allows direct interface to 3.0

V and 1.8 V SIM cards with no external components.

An integrated battery charger control circuit provides charging

capabilities for multi-chemistry batteries.

The CX20524-12 is packaged in a compact, 160-pin (12 mm x

12 mm) Fine Pitch Ball Grid Array (FPBGA), shown in Figure 2.

The CX20524-13 is packaged in a compact, 180 pin 10 mm x

10 mm, 0.5 mm pitch, Fine Pitch Ball Grid Array (FPBGA),

shown in Figure 3.
